Iran's new spy drone – Iran says it was able to commandeer the U.S. drone, rather than shooting it down.

"We've asked for it back. We'll see how the Iranians respond," Obama said.

"No nation welcomes other countries' spy drones in its territory, and no one sends back the spying equipment and its information back to the country of origin," Gen. Hossein Salami, deputy commander of Iran's military, said at the time, according to the semiofficial Fars News Agency.

In photos of Sunday's ceremony, the U.S. drone was on display alongside the Iranian copy.
